' To all whom "it may concern:

Be it known that We, lliii'iz lloFiiliNN and CARL COU'IELLE? oloeters of philosophy, ohen'iisle, citizens of the German Empire, resiclii g zit Elberfeld, Kingdom of Prussia, Gei'i'z'len Empire, have invented new ind useful lm provemeiiis iii Processes of Making Tetramethylendizmiin, of which the following is e s eoifioailaion.

( ur inven cion relates to a, new ailcl Villll able process for procluoing tetrziniethylenclim 211111 l ll-l -fll-L-Cll -Cl-l @H lil-L which is :1 valuable il'ltei'nicdiz te compound for the production of phzii'maoeuticzil -em11- pounds,clyestufile, etc.

The new process consists in treating the diamid of zulipic :iciol with solutions of halogens in caustic alkaline l yee.

ln order to illusti'utcllw new process more fully the following example is given, the parts being by Weight z--14-2 parts of chlorin are introduced into a mixture of 1000 penile of caustic soda lye (33 per cent) with. 15400 eel; our hands in the presence of parts oi ice. Subsequently 144 parts of the diemici of :iclipio aeicl are slowly :iolcleolv The tfilllpel'lvlllllfi rises to 70-80 C. while the diaimid-enters into solution. Against the end of the reaction the mixture is heated on "the water bath for 4 to 6 hours and the loose M1 -cH -oH -oH -oi i -iiii lmlogeii in. caustic alkaline lyes, euhstiii- Liz lly as described.

In testimony whereofv We have hereunto two subscribing witnesses.
